Trump's tweets continue controversial tone

NBC News — President-elect Donald Trump tweeted that "The world was gloomy before I won - there was no hope. Now the market is up nearly 10% and Christmas spending is over a trillion dollars!"

That's not the only controversial tweet Trump made Tuesday. He also said if President Obama had tried to run for a third term, Trump would have beaten him.

We're also getting a peek into the tone he plans to set in his inaugural speech come January 20th.

Trump is working with the same speechwriter who helped craft many of his speeches, including his convention address.

"Themes of which you've heard throughout the campaign, through the transition, and are representative in the inaugural that we're planning - themes of unity, themes of dreaming big - all those themes that uplift America," said Boris Epshteyn, senior Trump campaign adviser.

For now, the next president is delivering his message 140 characters at a time.

In his latest tweet storm, he's dismissing the United Nations as "just a club for people to get together, talk and have a good time."

That came in the wake of last week's security council resolution ordering Israel to halt settlement of Palestinian-occupied territory.

Trump opposed the measure and may be in a position to pressure the UN going forward.

"You know right now at the UN, seventy percent of the entire budget is spent on personnel and the United States pays twenty-two percent of the total budget," said Brian Hook, former assistant secretary of state for International Organization Affairs.

While critics say the future president went too far in speaking his mind on Israel, supporters say President Obama should have listened.

"And certainly to do something that you know is deliberately at odds with what the incoming president is going to do on a stage this big, I think shows a certain pettiness that I'm surprised to see in President Obama," said Rep. Tom Cole (R-OK).

Trump's tweet insisting he could've beaten President Obama is the most recent example of how the unexpected has become routine during a transition that's anything but traditional.

While Trump has announced plans to dissolved his charitable foundation to avoid conflicts of interest, New York's attorney general on Monday repeated that can't happen because the foundation is under investigation.
